[vtkusers] How to render realistic

[Jan Stifter]

dear users,
in the book "Scientific Visualization", there are so nice pictures of
renderered medical bones with vtk. Can anyone suggest me some values
for
a) diffuse/specular surface color
b) ambient/diffuse/specular light
c) opacitiy (probably 1.0)

so that bone looks like bone?

also, I would like to share values for metal and for plastic.

any hints are greatly appreciated
jan
